CO2 adsorption by activated templated carbons.
Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...
متن کاملUnderstanding Phenol Adsorption Mechanisms on Activated Carbons
The interactions between phenol molecules and activated carbons were investigated in order to understand the adsorption mechanism of this aromatic compound. A series of activated carbons with varied chemical composition but similar porous features were synthesized and submitted to phenol exposure from aqueous phase, followed by thermogravimetric analysis and identification of the desorbed speci...
متن کاملImproved phenol adsorption on carbons after mild temperature steam reactivation.
The purpose of this work is to explore steam reactivation at moderate temperatures of activated carbon exhausted with phenol, a highly toxic compound frequently present in industrial wastewater. The spent carbon was treated with steam at various temperatures (450, 600 and 850 degrees C) and times (from 5 to 60 min). Promising results were obtained by applying moderate temperatures and times. Wh...
متن کاملActivated carbons prepared from peanut shell and sunflower seed shell for high CO2 adsorption
Biomass wastes are considered as cost-effective and sustainable precursors to prepare activated carbons for CO2 capture. In this study, two biomass-derived activated carbons were prepared using peanut shell and sunflower seed shell, and the optimal activated carbons were obtained at low KOH/carbon ratio of about 1. The peanut shell derived activated carbon (P-973-1.00) and sunflower seed shell ...
متن کاملCO, Adsorption Techniques On High Surface Area Activated Carbons
For years the subject of CO, adsorption on activated carbons has been both challenged and supported. The question remains whether or not CO, is a valid adsorbate for characterizing pore structures of activated carbons. The predominance of nitrogen adsorption as a routine experimental technique for BET surface area approximations has more or less overshadowed the limitations of this technique in...
